Support for Kolmogorov-Smirnov (KS) test of Normality

In an Empirical study using many different types of data, the Kolmogorov-Smirnov (KS) test demonstrates better performance than other normality tests, especially in cases where underlying distribution exhibits fat-tails, skewness, and multi-modality.

We request adding support for KS test of normality in NumXL.
